Ozone layer exhaustion is the diminishing of the ozone layer present in the upper air. This happens when the chlorine and bromine particles in the climate interact with ozone and annihilate the ozone atoms. One chlorine can annihilate 100,000 particles of ozone. It is annihilated more rapidly than it is made. A few mixtures discharge chlorine and bromine on openness to high bright light, which then, at that point adds to the ozone layer consumption. Such mixtures are known as Ozone Draining Substances (ODS).The ozone-exhausting substances that contain chlorine incorporate chlorofluorocarbon, carbon tetrachloride, hydrochlorofluorocarbons, and methyl chloroform. Though, the ozone-draining substances that contain bromine are halons, methyl bromide, and hydro bromofluorocarbons [1]. Chlorofluorocarbons are the most plentiful ozone-exhausting substance. It is just when the chlorine iota responds with some other atom, it doesn't respond with ozone. Montreal Convention was proposed in 1987 to stop the utilization, creation and import of ozone-exhausting substances and limit their fixation in the climate to secure the ozone layer of the earth.
